A History of Doing More for Our Clients

Gray, Gray & Gray, LLP has been one of New England’s leading independent business consulting and accounting firms for nearly 80 years, and has grown to become one of the Top 200 firms in the U.S. We were among the first firms to take an integrated approach that combines business advisory services with tax, audit and wealth management to provide our clients with the power to do more.

The firm was founded in 1945 by Robert Gray, who was soon joined by his brothers, Milton and Mervin in their downtown Boston office. In 1947, the Grays became the first brothers ever simultaneously elected to membership in the American Institute of Certified Public Accountants.

Growth Through Acquisition


The firm was founded by the late Robert Gray. Robert’s brothers, Milton and Mervin, soon joined him in the firm’s downtown Boston office.

Gray, Gray & Gray acquired Kenneth Elgart & Company, a well-established accounting firm that specialized in serving franchises, in particular owner/operators of McDonald’s restaurants.


The firm acquired Clark R. Rattet & Co., P.C., an accounting firm that specialized in employee benefit audits, to further enhance that critical client service.


Gray, Gray & Gray merged with Patterson & Gerry, LLC, of Framingham, Mass., further expanding the client base and scope of services, including a new focus on emerging businesses.


Gray, Gray & Gray acquired O’Toole & Company of Boston, Mass., an accounting firm with a long standing and prestigious reputation in the Architecture, Engineering and Interior Design industry. This merger has contributed to the expansion of Gray, Gray & Gray’s AED niche.


Gray, Gray & Gray, LLP merged with Green & Green, LLC, of Dedham, Mass. Both firms provide accounting, audit, tax strategy, estate planning, and business advisory services to individual and corporate clients. The combined firm, operating as Gray, Gray & Gray, LLP, allows us to offer a wider and deeper range of client services.

Present Day

Over the years, Gray, Gray & Gray has resisted the temptation to be absorbed by other, larger accounting firms. We have made a conscious decision and commitment to remain independent. We owe it to our clients to keep our focus on them, and to continue to give them the high level of service we have always delivered.

I am most proud of our reputation for honesty and integrity… Our name is very well thought of. Through the years, we have treated our clients well and fairly.
